基于文件的proftpd磁盘配额quota

　　使用Ports安装proftpd，并把mod_quota选上，不过装完后没有找到ftpquota命令。只好又./configure –with-modules=mod_quotatab:mod_quotatab_file&&make，把ftpquota拷出来。

　　首先编辑proftpd.conf
QuotaLimitTable file:/usr/local/etc/ftpquota.limittab #Limit文件
QuotaTallyTable file:/usr/local/etc/ftpquota.tallytab #Tally文件
QuotaDirectoryTally on #是否记录目录操作
QuotaDisplayUnits Mb #客户端显示的容量单位
QuotaEngine on #是否启用quota
QuotaLog /var/log/ftpquota.log #日志文件地址
QuotaShowQuotas on #是否响应SITE QUOTA
QuotaOptions ScanOnLogin #登录时扫描用户home目录更新文件大小和数量

　　Limit文件记录配额，Tally文件记录已经使用的配额。ScanOnLogin则会在用户登录时扫描用户home目录，更新uploaded文件大小和数目，因为mod_quota只会记录该用户通过ftp的操作，使用ScanOnLogin可以保证Tally的uploaded文件大小和数量和用户home目录的一致。不过我把QuotaOptions ScanOnLogin注释了，因为我要限制的是上传量，但是不想把那些提供下载的文件也包含进去。不过这样就要手动修正已使用配额，当然也可以写脚本定时将/uploads的文件大小和数量自动写入tally文件。

　　再来建立配置文件：
先把limit和tally两个文件建立了
/home/yaoge123# cd /usr/local/etc/
/usr/local/etc# ftpquota --create-table --type=limit
/usr/local/etc# ftpquota --create-table --type=tally
下面添加一个限制，硬性限制ftp这个用户最多上传1000个文件，总大小最多1G
/usr/local/etc# ftpquota --add-record --type=limit --quota-type=user --name=ftp --files-upload=1000 --bytes-upload=1024 --limit-type="hard" --units="Mb"
–add-record –type=limit 增加一个limit限制信息
–quota-type=user –name=ftp 限制对象是用户名是ftp
–files-upload=1000 –bytes-upload=1024 限制上传1000个文件，总大小1024Mb
–units=”Mb” 说明上面的那个1024的单位是Mb
–limit-type=”hard” 硬性限制，到达限制容量就强制中断上传

使用ftpquota –show-record –type=limit可以查看已有的配额
/usr/local/etc# ftpquota --show-record --type=limit ftpquota.limittab
-------------------------------------------
Name: ftp
Quota Type: User
Per Session: False
Limit Type: Hard
Uploaded bytes: 1073741824.00
Downloaded bytes: unlimited
Transferred bytes: unlimited
Uploaded files: 1000
Downloaded files: unlimited
Transferred files: unlimited

使用ftpquota –show-record –type=tally可以查看已经使用的配额
/usr/local/etc# ftpquota --show-record --type=tally
-------------------------------------------
Name: ftp
Quota Type: User
Uploaded bytes: 0.00
Downloaded bytes: 0.00
Transferred bytes: 0.00
Uploaded files: 0
Downloaded files: 0
Transferred files: 0

使用ftpquota –update-record可以修改limit和tally。下面是一个修改和清零tally的例子：
/usr/local/etc# ftpquota --update-record --type=tally --quota-type=user -name=ftp --files-upload=100 --bytes-upload=100 --units="Mb"
/usr/local/etc# ftpquota --show-record --type=tally
-------------------------------------------
Name: ftp
Quota Type: User
Uploaded bytes: 104857600.00
Downloaded bytes: 0.00
Transferred bytes: 0.00
Uploaded files: 100
Downloaded files: 0
Transferred files: 0
/usr/local/etc# ftpquota --update-record --type=tally --quota-type=user -name=ftp
/usr/local/etc# ftpquota --show-record --type=tally
-------------------------------------------
Name: ftp
Quota Type: User
Uploaded bytes: 0.00
